Lecture 1 : Basic concept of pavement analysis and design
 
   Recapitulation
 
 

The present module highlights the basics of analysis and design of bituminous and concrete pavements. Pavements are analysed as layered horizontal structure with given elastic moduli and Poisson's ratio. Concrete pavement, in general, is made up of discrete slabs - therefore, it has joints both in longitudinal and transverse direction. A pavement is designed from structural, functional and drainage considerations. Fatigue and rutting are two major modes of structural failure of pavements. For concrete pavement design, temperature stresses are also considered along with stresses due to load. A pavement designer does not design a pavement for the ultimate load the pavement can carry, rather, the number of repetitions that the pavement can sustain.
